Configuring Parameters For Igmp Messages; Configuration Prerequisites; Configuring Source Ip Addresses For Igmp Messages - HP MSR2003 Configuration Manual

You can configure parameters for IGMP queries and responses for the current VLAN in VLAN view or
globally for all VLANs in IGMP-snooping view. If the configurations are made in both VLAN view and
IGMP-snooping view, the configuration made in VLAN view takes priority.
Configuring the global parameters for IGMP queries and responses
Step
1. Enter system view.
Enter IGMP-snooping view.
2.
3. Set the maximum response
time for IGMP general queries.
4. Set the IGMP last member
query interval.
Configuring the parameters for IGMP queries and responses in a VLAN

5. Set the IGMP last member
query interval.

Configuring parameters for IGMP messages

This section describes how to configure parameters for IGMP messages.

Configuration prerequisites

Before you configure parameters for IGMP messages, complete the following tasks:
• Enable IGMP snooping for the VLAN.
Determine the source IP address of IGMP general queries.
•
Determine the source IP address of IGMP group-specific queries.
•
Determine the source IP address of IGMP reports.
•
Determine the source IP address of IGMP leave messages.
•
• Determine the 802.1p precedence of IGMP messages

Configuring source IP addresses for IGMP messages

After a Layer 2 device receives an IGMP query whose source IP address is 0.0.0.0 on a port, it does not
enlist that port as a dynamic router port. This might prevent multicast forwarding entries from being
correctly created at the data link layer and eventually cause multicast traffic forwarding failures.
